I have an 08 GT and my power seat/lumbar button died. Took it to the dealer and they said fuse blew. Replaced it and good to go. Month later its dead again. Car is stock, no electrical changes. Anyone else had this problem?

Im at 26000 miles and really want them to find the cause before its out of warranty.

 

I will assuming that the seat moves freely, and it's stuck or hung up on something.

Not sure of the exact motor being used for the lumbar support, but it's possible that the device is trying to pull too much current; thus, blowing the fuse. Verify a clean 12v to the seat. Otherwise, I would think the motor itself is either worn, or something inside is causing excessive resistance.
